So I went and got my engine the other day after what almost felt like a year. I was just happy to get it. Well I get home and I notice they don't have exhaust sleeves in the engine. Now he gave me 2 TII rotor housings, s4 turbo and manifold(in excellent condition) s5 mas sensor, 3rd gen lower intake manifold, on oil cooler line brand new, and a TII water pump. Now my question to ya'll is, what should I do as for as the exhaust sleeves go? I plan on turboing my engine after breaking it in. Any opinions on what I should do?

 

Just throw in some turbo-sleeves and call it good. You could probably find some for pretty cheap from some junk turbo housings. $25-30?

What's the story on the new motor? Like, what happened to the sleeves supposed to be in there?

 

I am not sure, I don't know if he forgot to put them in or what. No how are the sleeves supposed to stay in the housing? Will the exhaust manifold hold them in there or what?

 

ooooh... I see what you're saying.

That's not good. I can't quite visualize whether or not the exh. mani. would hold them in... I would hope so, because that's pretty heinous. You should definitely let your builder know--because you don't really want to run without the sleeves.

 

what would happen if you didnt run sleeves? i almost didnt but i found some in the nick of time... just wondering

 

Oh yeah, (you might already know this) but the sleeves are supposed to be held in by 'roll-pins', on the sides of the housings. So yeah... The motor would have to be completely disassembled to install the sleeves and roll-pins correctly.

 

Was the engine ported? Might be his porting "style" as to why there are no sleeves. There are some builders/people out there that port some gigantic exhaust ports and run NO sleeves due to size. Maybe this is the case? Did you get some kind of huge port job?

If you run no sleeves expect some higher water temps. The sleeves help put a barrier between the coolant that is flowing above it and protect it from getting hotter. There are people that run no sleeves in race AND street applications, you just have to be more careful.

 

Yess the engine was ported, I can see where the port marks are so that must explain it. So will it be safe to run with no exhaust sleeves right? Funny thing is he said I can put the TI sleeves in, but will the exhaust manifold hold them in?

 

No idea if the exhaust manifold will hold them in or not, never seen or tried.

It will be safe but you just have to watch things. Get the basic gauges and make sure your cooling system is good. After that have fun and just watch stuff. Like I said, there are people that have, and still do, run with no exhaust sleeves (due to porting) on the street and in race applications. I don't do or suggest that style of porting, but it's done by some.

 

I just took a look at a spare s4 TII manifold and some Turbo housings I've got sitting around, and it does appear that the mani. would keep the sleeves in place, however that doesn't guarentee a tight fit... Perhaps some light 'chattering' without the pins holding them in, perhaps not...

I wouldn't personally run without the sleeves, simply because a MASSIVE, sleeve-less port on a turbo-car would probably hurt power, as opposed to helping... The turbo would probably spool slower without the 'tight' velocity that a good streetport would provide. I really don't know though (because I've never done it), so I'm just kind of making this up.

Just talk to the guy and ask his for his reasoning behind the lack of sleeves, to at least get the builders perspective.

 

I will do that and let ya'll know what he says. I wouldn't be suprised if he says, oh, I forgot those?

 

That just doesn't sound right at all. Ask him what's up with that.

 

Agreed.

Who built your motor? What kind of porting did they do?

There is absolutely no reason they should leave the sleeves out, especially on a street driven car.

 

DON'T INSTALL THE SLEEVES WITHOUT THE ROLL PINS.
They are not snug, and they will rattle like a ****-off rattlesnake with the engine running.
It almost sounds like detonation!
It will drive you crazy!

You can get generic roll pins from like Home Depot and open them up to make them snug.
The Home Depot ones are standard, so they are a little loose.
I just pried them open a little and hammered them in.

But my only concern is, can I do this with out taking the engine apart? Another thing is one of the studs that you bolt the exhaust manifold to is pretty messed up and I need to take it out. How, I have tried with pliers, channel locks, I can get the damned thing off. Can anybody suggest something that might help?

 

You cannot install sleeves WITH roll pins unless the engine is apart.

Can you thread a nut, actually 2, onto the messed up stud? If so do this. Thread one on far enough to be able to thread the 2nd on after it. Thread the 2nd on. After that get a wrench and tighten the INNER nut against the outter nut so it is tight, you can get it really tight if you use a wrench for both obviously and tighten them together. Then loosen the INNER nut (ie left). It should unthread the stud from the housing, then you can put a new one in.

If it is too messed up to thread nuts on get a stud extractor from sears.

 

Well I can't even get a nut on the stud. I was also told to drimmel the tip of it to try and use a flathead screw driver to try and get it out. Now after I get it out...How should I put the new ones in with out messing them up?

 

quit messing with it and take it back to the guy.......you've waited long enough only to hear: "you damaged it and we won't cover it," call the guy and have him take care of it.........or you can run it without the sleeves and as said above watch temps with aftermarket guages(stock are not as accurate).........just don't touch it anymore.
